Principal Scientist

About Me

I am a Principal Scientist within the External Collaboration and Experimentation (Experimental and Translational Medicine) area at Novo Nordisk. My expertise lies in quantitative evidence synthesis, data fusion, HTA and observational science, and in driving external engagement and collaboration. I am currently developing statistical and causal inference methods for the synthesis of evidence across different data sources. From December 2025, I have joined the Department of Statistical Science at University College London as an Honorary Research Fellow.

I have ample experience as a statistician, researcher and statistical consultant, providing support to the pharmaceutical, biotechnology, and healthcare consultancy sectors. Prior to my current role, I was a statistical methodologist at Novo Nordisk and the lead statistician for health technology assessment at Bayer Pharmaceuticals. Prior to that, I was an independent contractor providing statistical support to contract research organizations such as IQVIA and ICON plc, and public bodies such as SickKids.

Research

My research lies on the interface between statistics and health technology assessment, involving both methodological and applied problems. My primary interests are the development of statistical methodology to compare treatments in the absence of head-to-head clinical trials, adjusting for differences in patient populations and overcoming limited access to subject-level data.

Current interests: indirect treatment comparisons, covariate adjustment, transportability, estimands
